Probably i've found the issue ... will be fixed in next build.

Actually MM window turns to white and freezes on that mode.

Did you sent bugreport ? If so do you know bug ID ?

Although it seems to be fixed and verified here: https://www.ventismedia.com/mantis/view.php?id=15555
But I am still experiencing the same problem while playing music in 2167. Just try to change skin for several times. (have deleted persistent.json)

Will check.

While playing a track I tried to change the skin ... the music kept playing but the screen went blank and never came back.
This was on a brand new install. from default skin to Monkey Groove

Came back with id when killed. 46CB85A7
